Hi there.
00:03
In this question, we are using a bunsen burner, which is, of course, an open flame.
00:11
All right.
00:12
So this can be hazardous, if not treated with respect, if we are not cautious around it.
00:20
All right, so there are some precautions that we need to take when using it.
00:25
First one, well, it's a flame, so we don't want other things to catch on fire.
00:31
So we do want to keep flammable items away from the burner.
00:46
Don't want to catch other things on our lab station on fire.
00:51
Okay, the next one, let's look at the next one.
00:54
Do not reach over a lit burner as the flame may be difficult to see.
00:58
Yes, that's also a good practice.
01:00
Do not reach over a flame.
01:12
Just as an example, i had a person wearing a fuzzy sweater once and they were reaching too close to the flame and all those little fuzzy hairs that stuck out on the sweater, lots of oxygen surrounding those, they did catch on fire.
01:28
She was fine, but nonetheless, you do not want to reach over or get your clothing near that open flame.
01:35
All right, what's next here? the burner should be stable on a level surface.
01:41
Yes, indeed.
01:42
We don't want to stack it up on, i've seen, sometimes seen students stack the burner up rather than moving the ring stand lower.
01:53
So you don't want to put a nice little jenga stand under your open flame.
01:58
You don't want it falling over and catching things on fire.
02:01
So it should be stable and level.
02:03
No jenga towers under your bumsen burner...
